Christina Purdin, 28, was airlifted to Miami Valley Hospital, but she died Monday from her injuries.

Her husband, Mike Dunn, said Purdin was struck by a man he'd hired to so some painting, but he said the man never showed up after receiving payment upfront.

Dunn said he repeatedly called the man, whom he identified as Dustin Watkins, about the money, and he said Watkins stopped by Sunday evening to discuss the matter.

Dunn said Watkins came with a woman who appeared to be on drugs, and he said she screamed at Watkins not to give the money back.

Watkins then got into a car and sped away, Dunn said, and Purdin's arm got stuck in a seat belt and she was dragged about 40 feet before she was thrown under the car.

"He took off, and Christina's hand was on top of the car, and the seat belt latched around her hand and he drug her on down to here," Dunn said. "When she fell she was lying down, and he rolled all the way up her whole left side, all the way up to the back of her head."

Purdin was the mother of two boys and a girl.

Officers arrested Watkins, 23, and charged him with fleeing the scene of an accident, tampering with evidence and possession of drug abuse instruments. Police said he had a hypodermic needle.

They also arrested Maria Misquez, 31, and charged her with complicity to fleeing the scene of an accident.

Police said the pair had a lengthy criminal record. Watkins has been arrested since 2003 for driving with a suspended license, robbery, assault and unlawful sexual contact with a minor. He was sentenced to 11 months in prison for the sex crime charge, and the judge in that case said Watkins showed no genuine remorse.

Watkins has been arrested previously this year for a seat belt violation, petty theft and possession of drug paraphernalia.Misquez has been arrested since 200 for obstructing official business, petty theft, disorderly conduct, complicity to aggravated robbery, intoxication and driving under a suspended license.
